Abstract (en)

[origin: US2013028659A1] The invention relates to an apparatus and to a process for cohesively joining two plates (1 and 2) having differing melting points, one of which plates, the end plate (1), includes a light metal material, in particular aluminum material, and the other of which plates, the connecting plate (2), includes an iron and/or titanium material, wherein a coating (9) preferably on the basis of zinc or aluminum is provided at least partially on at least one of the abutting faces (3′, 3″) of the abutting edge (3) of the connecting plate (2) which extend inclined with respect to one another, in which process both plates (1 and 2) are joined together by braze welding so as to abut against one another along their common joint using an additional material (5) on the basis of light metal, in particular on the basis of aluminum. In order to provide advantageous process conditions, the invention proposes that a recess (10) be made, before joining, in the abutting edge (4) of the end plate (1) for receiving at least part of the coated abutting edge (3) of the connecting plate (2), wherein, during joining, braze welding is carried out at least partially over a flank (11 or 12) of the recess (10) overlapping the coating (9) of the connecting plate part.
